Voyager 1's Journey Through our Solar System in Photographs

In a recent Reddit AMA to commemorate the craft's leaving of our solar system, a Voyager 1 team member (name unverified) commented that all cameras were turned off permanently after the iconic "Pale Blue Dot" photograph was taken on Valentines day in 1990. Between then, and its launch date on Sept 5, 1977, hundreds of thousands if not millions (exact number unknown) of photos have been taken by the craft on its journey. These are just a few.

Sept 18, 1977 - 7.25 million miles from Earth, Voyager 1 captures our planet and it's moon cut in half by the light of the sun.

Jan 6 to Feb 3, 1979 - Voyager's 60 day approach of Jupiter, titled "Blue Movie" due to the blue filter it was shot through.

Feb 13, 1979 - Jupiter and two of its satellites (moons), Io (left) and Europa (right).

Date Unknown - Jupiter's "Great Red Spot" (top right)

Date Unknown - Volcanic surface flows on Io

March 4, 1979 (?) - Explosion on the surface of Io

Nov 5, 1980 - Northern hemisphere of Saturn from 5.5 million miles away.

Nov 12, 1980 - Saturn's moon, Rhea's surface from 79,500 miles away, heavily cratered due to an estimated life of 4.5 billion years.

Nov 16, 1980 - Saturn and it's rings, shown as a crescent due to light and camera angles.

The Voyager 1 is part of the two unmanned-craft "Voyager Program" (alongside Voyager 2), which was created by NASA and sent into the cosmos in 1977 to perform tests and gain knowledge about our solar system, specifically the composition of planets and their moons. The technology aboard both of these crafts is very simplistic by today's standards, and all of the above photographs were taken by analog film cameras and scanned, the colors created by a mix of channel blending, and digital recreation. In September, 2013, NASA's JPL (Jet Propulsion Lab) confirmed that Voyager 1 entered interstellar space on August 25, 2012, making it the first man-made object to access this region. NASA estimates that both Voyager crafts have enough power to continue regular operations until 2025, when they will power down and drift throughout our universe indefinitely.

Actually, this is not true. The Voyager used a TV camera, calibrated against radio interference (a sort of "noise reduction", if you will), and sent these images back to earth in a radio signal. "Scanning" actually refers to the line scans of a TV feed :)
